It is relatively straightforward. If the agreement is made with the remaining countries and there is not the time to put it through the CRaG process before 31 December, it has the potential to be provisionally applied. The terms of that agreement will remain on 1 January in accordance with the existing EU deal going into that time, so there should be no interruption for businesses. Parliament will still have the opportunity, under the CRaG process, to give that agreement full scrutiny.
